Yeah, Pointman is really difficult, but for superfast parts there is trick: Play it like Mono! Just run into yellow and red (or only just red) blocks, try to not to hit too many other blocks, and if you do, collect some more to make a match so they disappear again (by using the Pointman ability this is not so difficult). And it might be better to avoid whites most of the time, they have a tendency to make things very complicated if two of them land in the wrong place.
You don't really get the maximum amount of points that way, but it works surprisingly well.
Also, glad you enjoyed it, anyone else want to try?
